Application context
Why this design is used
Application guidance is derived from the product family and tied to the model-specific selection fields above.
Focus and conjugate setting
Position a lens along the axis to place image and Fourier planes where the design requires.
Centration adjustment
Bring the optical axis of the lens onto the axis of the beam rather than the mechanics.
System integration
Integration and compatibility
Use these checks to connect NLB50.8-B to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optic it accepts
- Clear Aperture A (mm): φ46 · Optics Size B (mm): φ50.8
- Check diameter and thickness together. A holder that accepts the diameter can still fail to retain an optic that is thinner than its minimum, and clear aperture is normally smaller than the optic the mount holds.
- Mounting interface
- Mounting Hole: M6
- Match the thread standard and hole pitch before ordering. Metric and imperial hardware interchange only through an adapter, and a thread that is nominally similar is not necessarily the same pitch.
